ABSTRACT:
A method of producing a fixed-bed catalyst with nano-scale structure using a nano-powder production reactor and a filter, the method comprising: introducing a starting powder into the reactor, wherein the starting powder comprises catalyst material; the reactor nano-sizing the starting powder, thereby producing an output, wherein the output comprises a nano-powder entrained in a fluid stream, the nano-powder comprising a plurality of nano-particles, each nano-particle comprising the catalyst material; introducing the output from the reactor to the filter structure, wherein the filter structure is fluidly coupled to the reactor; the filter structure separating the nano-particles from the fluid stream, wherein the fluid stream flows through the filter structure, while the filter structure collects the nano-particles, thereby forming a structured collection of catalytic nano-particles on the filter structure; and removing the filter structure from the reactor, wherein the structured collection of catalytic nano-particles is maintained for use as a fixed-bed catalyst.
